4.3 DIVER CONNECTIONS
4.3.1 DIVER MICROPHONE
–
This is a dual 5-way binding post jack (color-coded red)
that functions as both an output (earphone) and input (microphone) for the diver as
controlled by the PUSH-TO-TALK BUTTON and PUSH-TO-TALK JACK. Using this
connection, the diver can be wired in either 2-Wire or Full Duplex (4-Wire) mode
regardless of the mode used for the diver.
To connect the diver in 2-Wire mode, connect both the diver microphone and
earphone to this jack. If the diver umbilical uses banana plugs, simply stack both
plugs into this jack as shown in the wiring diagram in section 4.8. In this mode, the
diver microphone will be active and heard on tender headset and/or PANEL
SPEAKER unless the PUSH-TO-TALK BUTTON or PUSH-TO-TALK JACK is used.
When a pre-amp microphone is used in the 2-Wire mode setup, it is required to
have special speakers supplied only by Amron. Contact Amron for more
information.
To connect the diver in Full Duplex (4-Wire) mode, connect the diver microphone to
this jack and the diver earphone the DIVER EARPHONE jack as shown in the
wiring diagram in section 4.9. The diver can use this mode even if the tender is
